The patch titled
Subject: timerfd: export defines to userspace
has been removed from the -mm tree. Its filename was
timerfd-export-defines-to-userspace.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Frysinger <vapier@xxxxxxxxxx>
Subject: timerfd: export defines to userspace
Since userspace is expected to call timerfd syscalls directly with these
flags/ioctls, make sure we export them so they don't have to duplicate
the values themselves.
